This'invention relates to improvements in Work supports and isillustrated herein as embodied in a fastening inserting machine of a.type used in' the manufacture and repairing of shoes. y

In the repairing of shoes the thickness of the work piece into whichfastenings are inserted varies over a wide: range. Thesame machine isused, for example,both to attach m soles to shoes by all-around staplingand to attach top; lifits to heels of varying heights. It-is,accordingly, desirable to provide a work support, the height of whichcan beadjusted rapidly and with a minimum of labor. Since work supportsused on metallic fastening inserting'machines, particularly when thework is. to be: performed off the last as in the case of-all-aroundstapling or nailing, are commonly provided with a clenching cavity therelation of which to the line of drive is critical, it is necessary soto construct the work support: that heightwise adjustment thereof willnot affect the position of the clenching cavity transversely of the lineof 251 drive; On. the other hand, for example to facthitate the" settingup of the machine, it is necessary to. provide means by which the position of the clenching cavity can be adjusted transversely of the line;of drive.

invention to provide animproved work support" adapted for use in:fastening inserting machines ofi the-type used in the manufacture andrepairing of? boots and shoes of such a character that its height can bemore quickly and conveniently adjusted than is the case with: theconstructions of: the prior" art. Itis a: further object. of theinvention to provide anaimproved work support of such a nature .by theoperator toward its work clamping position when the machine is at rest.As-illus- It is, accordingly, anobject of the present thatthe worksupport can be adjusted heigh*- struction; being of such a nature thatthe horn is held by the pawl and ratchet against movement away from itswork supporting or clamping position (against downwardlmovement, asillustrated) but can be freely moved trated, the; pawl is provided witha tail or handle projecting outwardly so that it can be convenientlymanipulated to release the sup port. This can be done by merely strikinga light blow upon the tail of the pawlby downward movement of the handof the operator. Such a construction perm-itsthe ad to each other andusing his other hand to steady thewo'rk piece if necessary. .As he hitsthe horn to the desiredposition the ratchet clicks past the horn andholds the horn against downward movement.

In accordance with another feature ofthe invention, the illustratedmachine: 1s provided with improved means for making, and

maintaining the adjustment of the clenching surface" of thehorn'transversely ofthe line of drive at all times, regardless of theheight wise, adjustment of the work support. For this purpose a hornsupporting or bracket member, which is secured to the horn post for.rotation about the line of drive, is provided: with an upstanding rodsurrounded by collarslidably mounted thereon and provided with a socketillustrated-as an undercut bayonet slot receiving aba-ll formed on theend of an adjusting screw threaded through the horn and normallysecured'in p0- siti'onby a lock nut. Thecollar slides verti-" cally onthe rod as the horn is adjusted heightwise and thus prevents transversemovement of the horn relatively to the horn support and accordinglyrelatively to'theline of drive. f

With' the aboveandotherobjects and features in view the inventionwillnowbe de-' 100 of drive.

scribed with reference to the accompanying drawings and pointed out inthe claims.

In the drawings: I Fig. 1 is a side elevation of a staple insertingmachine provided with a work support embodying the present invention;

The work support of the present invention is illustrated herein asembodied in a fasten ing inserting machine having staple forming andinserting instrumentalities of the character disclosed in Letters Patentof the United States No. 1,016,930, granted February 13, 19152 on anapplication filed in the name of William H. Borden to which referencemaybe had 'for a fuller disclosure of --such parts of the machine as itis unnecessary to describe and illustrate herein. 'this machinecomprises a column carrying at its upper end a head 12 provided withwire feeding rolls 14 (Fig; 2) from which a wire 16 is fed to a pair ofknives 18 which sever "from it suitable lengths for the formation ofstaples. -The staples are formed from the In brief wire 16 by relativemovement of an inside former 20 and outside formers 22, staples beingdriven through a nozzle 24 by a driver 26.

The staple forming and inserting instrumentalities are operated from amain drive shaft 28 to which power is transmitted by clutch mechanism 30from a belt pulley 32.

1 The clutch mechanism 30 is controlled from a treadle 34 (Fig. 1)through a treadle rod 36, the arrangement being such that depression ofthe treadle 34 beyond a point determined by a lost motion connection 38trips the clutch and causes the operation of the fastening insertinginstrumentalities.

The machine is provided with a horn post 40 mounted for vertical slidingmovement in I a sleeve 42 carried by a bracket 44 secured to the column10, the horn post 40 being raised throughconnections 46 by the earlierportion of'the depression of the treadle 34 in a wellknown manner sothat the work piece in which a'fastening is to be inserted (for ex 7ample a shoe to which a sole or a half-sole is to be attached byall-around stapling or a shoe having a heel to which a top-lift'is'to beattached) is clamped under a relatively heavy spring pressure before theclutch is tripped.

Mountedat the top of the horn post 40 i for rotary movement about theline of drive is a bracket 50 provided with vertical ways 52 slidablyreceiving a downwardly extending stem 54 carried by a horn 56. The stem54 of the horn 56 is provided with a ratchet 58 cooperating with alpawl6O pivoted at 62 to the bracket 50 and yieldingly held in engagementwith the ratchet 58 by a spring 64 so that the horn 56 can be movedupwardly while the machine is at rest without interference by the pawlbut is held against downward movement except when the pawl 60 ismanually released. The pawl 60 is provided with a substantiallyhorizontal tail or handle 66 projecting outwardly so that the pawl 60can be released from the ratchet 58 by a light blow struck on the tail66 by a downward movement of the hand of the operator. 1 I

The-bracket 50 carries an upstanding rod 68 adjacent to the horn 56.Slidably mounted on the rod 68 is a collar 70. The collar 1 '70 isprovided with an undercut groove 72 in the form of a bayonetslot/receiving a ball 7 4 formed on the end of a screw 6 threaded in ahole formed in the horn 56 and clamped inadjusted position by a lock nut78 Thus 13,.

it will be seen that transverse movement of the horn 56 relatively tothe bracket 50 is prevented by. engagement. ofthe screw '76 with thecollar and heightwise movement of the horn is in no way interfered with.To

prevent the escape of the collar 70 from the rod 68 by excessive upwardmovement ofthe. horn 56 a collar '80 is secured to the upper end of thehorn 56. When it is desired to adjust the position of the clenchingcavity 82?. carried at the end of the horn 58, either in setting up themachine or otherwiseyit is only necessary to release the lock nut 78,

turn the screw 76 to make the desired adj ustment, and then tighten upthelock. nut. In this way the desired. critical adjustment of theclenching cavity relatively, to the line of drive can be easily made.

Assuming the work support to be insuch a position that the horn 56 istoo high to re'.' ceive the work piece whichis to be presented to themachine, the operator strikes the'han dle 66 of the pawl 60 thusreleasing the'pawl from the ratchet 58 so that'the horn descends to itslowermost position. Then he places the work piece on the horn 58,holding the work piece between the end. of the horn 58 and the nozzle 24and at the same time grasping the portion of the horn .58 adjacent tothe work piece with one hand so that he can move the horn and the workpiece upward- 1y until the horn is spaced the desired distance below thenozzle of the machine. After the ho'rn has been adjusted in this mannerhe depresses the treadle 34, first causing the:

work piece to be clamped between'the horn 56 and the nozzle 24 andthereafter tripping the clutch thereby causing the insertion of astaple.

While the member 56 of the work support-- oftheillustrated machineisspoken of in this specification and the accompanying claims asa horn itshould be understood that this-is merely as a matter of convenience andis n'ot'intended as a limitation. Obviously the invention is not limitedin its scope to a construction in which the work carrying'memberis of acurved formation of the general Character herein disclosed and it is notintended that the claimsshall be construed as construction being suchthat the horn'isautomatically held by the pawl and ratchetagainstmovement relatively to the horn carrier away from its worksupporting position but can be freely moved by the operator toward itswork clamping position when the machine is at rest.
